Figure 9: In Figures 7,8,10 E1 and E2 is replaced with the actual values (can be seen in Figure 10 in the submission; 1,1), while in Figure 9 this was missed (probably copy-paste-error): Is E1, E2; should be 0, 1

Figure 9 and Figure 10: In the rest of the RFC and all the other figures, the field is called "Ext. Sequence Number" and not "Ext. Sequenz Number" (Looks like a translation error).
